I have no excuse, except ignorance but now I will devote a significant amount of time exposing this product and the problems it causes.
I used the “spot-on” treatment on my 12 lb cat. I used the product for cats in EXACTLY the manner prescribed on the box. Today my cat is the Er receiving IV fluids. She will live, but bill will probably be 300.00. Hartz will pay this bill and the supermarket where I bought it will also remove the product from it’s shelf if I have any say about it.
